Performance: Pieces are destroyed and created every time

Currently, the Pieces are dynamically loaded and draw at run-time.
When in the Review mode, pieces are re-created (using new Image()) and then 
load() and then 
re-add to the parent again.  As a result, the App needs to contact the server 
every time the user 
clicks on any of the Review button.  We must change the code to improve the 
performance 
because the majority of users (in Vietnam, China) will not have fast network 
connections (like we 
do here in US).

Note: In my other desktop HOXChess app, all the initial 32 pieces are created 
at one time and I 
never have to create a new Piece during the Table/Game 's life time.  When the 
Pieces are 
captures, they are simply hidden (invisible) from the view.

*** Note: As of now, the BoardCanvas class is too complex because it combines 
the UI code with 
everything else (like validation, review, ...). We must break this BoardCanvas 
into multiple class. 
Otherwise, it is too difficult to maintain and to improve.
